ROCK-DBILLING- MACHINE.

To all whom it may concern:

`Be it known that I, CHARLES C. HANSEN, a citizen of the United States, and resident of Easton, in the county of Northampton and State of Pennsylvania, have invented a new and useful Improvement in Rock-Drilling Machines, of which the following is a specilication.

This invention relates to improvements in rock drilling machines and has for its object to provide a suitable support such, for instance, as a wagon, a turntable thereon, a frame uprising from the turntable arranged to carry a tool of any character, suc'h asa rock drill, the rock drill being movable up and down along the frame.

A further ob]ect is to provide a device of this character in which a common means is utilized for propelling the wagon, swinging the turntable and controlling the movements of the rock drill.

In the accompanying drawings, Figure 1 represents the machine partially in side elevation and partially in vertical central section, Fig. 2 is a top plan view of the machine, and Fig. 3 is a detail horizontal section showing some of the driving connections between the engine and thev parts controlled v thereby.

The turntable' is denoted by 1 and its track by 2. An annular series of balls 3 is interposed between lthe turntable and track, forming a roller bearing for the turntable; The support for the turntable in the present instance comprises a wagon vhaving a vplatform 4, framework 5 and traction wheels 6'. A fixed frame uprises from the turntable, which frame comprises horizontal base members 7, vertical members 8 and diagonal members 9.

The rock drill is denoted by 10 and its saddle by 1l. This saddle is'fitted to move up and down along the vertical members of the frame. In the present instance the rock drill is fed downwardly to its work by gravity. A reversing hoistingI engine 12 is mounted on the wagon platform. This en vided with a winding drum 13 rom which the hoisting cable leads under pulleys 15, 16, 17, 18on the wagon; from thence upwardly through the center of the turntable and over pulleys 19, 20, at the top of the frame. From thence the cable passes downwardly around pulleys 21, 22,carried by the drill saddle 11; thence upwardly around a pulley 23 at the specification of Letters Patent.

top o f the frame. This engine 12 also serves to swing the turntable into its different positions as follows: The turntable is rovided on its periphery with teeth 24 which mesh with a pinion 25 on a vertical Shaft 26, which shaft also has a beveled gear connection 27, 28, with a horizontally arran 'ed shaft 29 mounted in the wagon frame. Tis shaft 29 is provided with a bevel gear 30 and a cross shaft 31 is provided with a bevel gear 32 which may be brought into` and out of en gagement with the bevel gear 30 by a hand clutch lever 33. This cross shaft 31 is further provided with v'a chain and sprocket connection 34, 35, 36, with the engine shaft 37. also arranged to propel the wagon in either direction as follows One pair of traction wheels`6 is connected to the engine shaft 37 through sprockets 38,

39, chain 40; sprockets 41, 42, chain 43; and

gears 44, 45. A hand operated clutch 46 is arranged to connect and disconnect the gear 45 and the sprocket 42. Suitable clamps 47 are provided for locking the turntable 1n its diHerent positions.

To insure a rigid support for the machine during the drilling operation, the base members 7 of the drill supporting frame are pro. jected outwardly a wagon and at their ends they are provided Patented May 19, 1914.

distance beyond the with one or-more adjustable braces 48 (in l two braces) which are form of screw jacks ardown into engagement the present instance herein shown in the ranged to be screwed with the ground.

In operation, the wagon is moved to the eration is' to be carried out by connecting t e engine to the traction wheels. The engine is then utilized for swinging the turntable to `the desired point where it may be locked by the clamps 47. The engine 1s then connected tot e drill and the drill is permitted to be fed by gravity to its work. After the hole has been drilled, the engine may be used for` lift-in the drill. It may then be used for swinging the turntable into another position or it may be used for moving the wagon to as desired.

It will thus be seen that a very simple means is employed for carrying out the several operations Vherein described.

While I have chosen to show and describe my invention in connection with a rock drillv movable along the frame, it is to be 'understood that a. tool' of any character may be employed Without departing from the scope of my invention. It is also evident that various changes might be resorted to in the construction, form and arrangement of the several parts Without departing from the spirit and scope of my invention; hence I do not Wish to limit myself strictly to the structure herein set forth, but

What I claim is l. A wagon, a turntable thereon, a frame uprising from the turntable, a rock drill movable along the frame and an engine mounted on the Wagon arranged to propel the Wagon and to swing the turntable.

2. A Wagon, a frame carried thereby, a rock drill movable along the frame and an engine mounted on the Wagon arranged to propel the wagon and to control the movements of the rock drill.

3. wagon, a turntable thereon, a frame uprislng from the turntable, a rock drill movable along the `frame' and an engine mounted on the Wagon arranged to propel the Wagon to swing 'the `turntable and to control the movements of the rock drill.
